SPECIFICATION forming part of Letters Patent No. 401,556, dated April 16, 1889.

Application filed January 15, 1389. $e1'ial No. 296,425. (No model.)

To all whom, it may concern.-

lie it known that 1, CHARLES HALLETT, a citizen of the United States, residing at Ohicago, in the county of Cook and State of lllinois, have invented certain new and useful. Improvements in Steam-Separators, of which the following is a full and exact description.

My invention relates to that class of steamseparators, so called, placed within a steamgenerating boiler above the water-line therein-that is to say, above the surface of the water contained in said boiler while steam is being generated therein, and in such position that such steam in passing from said boiler through the steam-outlet thereof for use in any manner or in any place wherein a dry steam, so called, is preferable to wet steam must necessarily pass through said separator.

Myinvention maybe applied to an ordinary horizontal'tubularboiler or to the dome thereof, and to an ordinary vertical tubular boiler; but in the drawings accompanying and forming a part of this specification I have illustrated my invention as applied to an upright radial tubeboiler.

Where steam is taken from boilers for use in obtaining motion by passing the same through a motor of any kind, it is very desirable that such steam shall enter and pass through said motor in as dry a form as possible, and it has also been found advantageous to superheat said steam, as it is termed, before it so passes to and through said motor. It is well known, too, that where steam-generating boilers are used for certain purposes, as in generating steam for actuating motors propelling small boats, it is desirable that said steam generating boiler be so constructed that the center of gravity thereof shall be as low as possible therein, and this is particularly essential where said boiler is a vertical boiler; and for this reason it is highly important to so design the boiler that there shall be as small an amount of metal therein above the water-line thereof as practicable, and that there be very little steam-space above the water contained in said boiler and between the upper end thereof and the surface of the water.

The object of my invention 1S to obtain a steamseparatorlwhich may be used alone and independei'itly of all other steam-separators for all the hereinabove-named purposes, and for others wherein a dry steam is desired, and which may, when required, be used in connection with and in addition to steam-sepcrators of the kind heretofore made.

'ln thedrawings, Figure 1 is an elevation of my invention designed to work as a steamseparator and super-heater, and applied to a boiler which I have found to be peculiarly well adapted to-be placed in a small steampropelled boat or launch for generatin steam actuating the motor of said boat. Fig. 2 is a front elevation of another manner of applyin g my invention to an upright boiler. Fig. 3 is the side elevation tl'iereof. Fig. 4: is a side elevation of my invention applied to an upright boiler in combination with a separator heretofore made and applied to said boiler.

As hereinbefore stated, I have illustrated my invention as applied to an upright boiler consisting of a vertical cylinder having radial tubes thereon extending outward from said cylinder through the furnace of said boiler above the lire-pot thereof to or nearly to the outer casing of said furnace; but it is evident that my inventioncan be applied to an upright tubular boiler or to a horizontal tubular boiler in substantially the same manner as it is applied to the boiler herein illustrated, the So radiating arms of the herein-illustrated boiler forming no part of my invention.

The device embodying my invention as applied to a boiler of the kind illustrated in Fig. 1 is constructed as follows: A is a boiler having radial tubes a a thereon. a is the water-line of the boiler, and a" the upper head or end thereof. 3- is the chimney of the furnace of the boiler. C is an. iron pipe, cylinder,or tube having a closed end, O, and secured at the other en d to head It of boiler A. 'lylinder 0 forms an extension of the boiler and is hereinafter referred to as tubular extension," 0. This tubular extension (1 may be constructed of the same material as boiler A is constructed of, and has heretofore been attached to said boiler A by securing a cast flange, 1), to the head of the boiler and fastening said tubular extension into said flange. E is the steam-outlet pipe. This steam-outlet pipe E passes through the easing of the furnace in this form of construe tion, through the furnace of the boiler above the fire-pot thereof, and into the boilerA above the water-line of said boiler. F is an extension of steam-outlet pipe E, and is connected thereto by an ordinary steam-pipe joint or coupling. Pipe Fextends inward toward the center of the boiler A and underneath tubular extension C, from whence it extends upward and into said tubular extension. ff are perforations in tube or pipe F in that portion of said pipe F contained within tubular extension C. G G is a wire-woven cloth wound around pipe F over that portion thereof within which perforations ff are made. I have found it desirable to use metal cloth having amesh not exceeding one-sixteenth of an inch in the open part thereof, and to wind or wrap said cloth twice or slightly more around pipe F. It is evident, however, that the number of times such cloth is wrapped around such pipe F is or may be controlled to a certain extent by the size of holes f in pipe F, as the purpose of cloth G used, as described, and in combination with the perforated pipe F, is to permit steam contained in tubular extension 0 of said boiler A to pass therefrom into pipe F, and from thence to steam-outlet E as such steam is required for use, and to prevent par ticles of water passing from said tubular extension C along with said steam and into said pipe F. It will be observed that in this construction steam-outlet E and the contents thereof are subjected to intense heat from the furnace B of said boiler in that portion of said steam-outlet E located between the shell or case of boiler A and shell or casing H of the furnace B, and the steam passing therefrom is thereby, to a certain extent, super heated.

In the form of boiler to which my invention is illustrated as attached in Figs. 2 and 3, wherein it is desired to .so construct such boiler that man-hole I may be pla'ced upon the top of the boiler, through which entrance may be had to the interior thereof, I have illustrated the device embodying my invention or a part thereof in a slightly-different form of construction. In this form of construction the waterline, it will be observed, must be relatively somewhat lower in reference to the upper end, a, thereof than in the boiler illustrated in Fig. 1.

I11 Figs. 2 and 3 E is the steam-outlet pipe. F F are pipes closed at the outer ends thereof, respectively, and having perforations fff therein and secured to steam-outlet pipe E at the inner ends thereof. In order that steam-outlet pipe E may be removed from the boiler when desired, I have placed an ordinary steam-coupling joint, 2, in steam-outlet pipe E in this form of construction, and when access is desired to the interior of said boiler the cover of man-hole I must be removed and that portion of steam-outlet pipe E to which pipes F are secured detached at couplingjoint 6 and removed from said boiler. G is wire-cloth wound around perforated pipe F in the same manner as hereinbefore described.

In the boiler constructed as in Fig. 4, wherein the steam is taken from the top thereof and a separator of the ordinary construction used in connection therewith, I have illustrated my device, or a portion thereof, applied to said boiler and working in combination with said separator in the following manner: J is the separator heretofore used on said boiler. K is a diaphragm in the boiler above the water-line thereof and having a hole therein, over which said separator J is placed. 7s k are drip-pipes extending through diaphragm K downward and below the water-level in boiler A. F is a pipe having perforations f f therein, as hereinbefore described, secured to separator J and to diaphragm K, and extending downward from said diaphragm into the steam-space between said diaphragm and the water-level of the boiler. The lower end of perforated pipe F is closed, and around the perforations f f is wound metal cloth, G, as hereinabove de scribed.

The operation of mydevice is as follows: When steam is generated in the boiler, it ascends therein and into the steam-space of said boiler, and as the pressure of the steam in such steam-space becomes sufficient it forces its way through the perforations in metal cloth G into pipe F, from which said pipe F it is taken for use in the ordinary manner. In practice I have found the steam issuing from the boiler supplied with my separator to be extremely dry, and no other separator to be required; but I have made use of my invention in the manner herein described, in combination with other separators, thereby improving the character of the steam obtained from said boilers.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a steam-separator, the combination of a pipe having one end thereof closed, perforations in the pipe, and metal cloth wound one or more times around the perforated pipe in close contact therewith, whereby steam entering the perforated pipe must pass through the meshes of the cloth, all substantially as described.

2. In a separator for steam-generating boilers, a pipe having perforations therein placed in the steam collector-or dome of said boiler formed by a tubular extension thereon of less diameter than said boiler, in combination with a metal wrapping having small perforations therein wound around the perforations in said pipe, and a steam-outlet pipe passing from said dome or collector through the furnace of said boiler, whereby steam generated in said boiler passing through said separator in leaving said boiler by said steam-outlet pipe shall pass through the furnace of said boiler above the firebox thereof, all substantially as described.

In a steam-separator, a pipe having pertending through the furnace surrounding the forations therein placed within a steanrg'enboiler above the fire-pot therein, all substanerating boiler above the Water-line tl1ereof,in tially as described.
